Hey, I don't want to come off like I'm just shilling for my company, but what you are trying to do may possibly be more easily done with a video hosting platform with an API.

By taking this approach, you won't have to worry about tuning encodes yourself, dealing with problem videos, etc. while also getting access to many other features that the client might be interested in (playlists, analytics, video SEO, etc.).

If you want to talk sometime and discuss various options and pros and cons for each, I'd be happy to help out. You can reach me at ben -at- wistia -dot- com. I'm the VP of Engineering there.
